porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the

temperature setting or the inside tem-
perature.

matically be registered to the electronic
key that was used to unlock the vehicle.

more than one electronic key is in the
vicinity or if the smart access system with

To let fresh air in, set the air conditioning
●
system to the outside air mode.

and outside the vehicle may enter into
and accumulate in the air conditioning
system. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on.

switches to fresh air intake mode to
encourage better air circulation through-
out the vehicle, helping to reduce odors
